Which Long Tube Headers?

Hey Guys, I am looking into buying some long tubes for my 5.3. Its a 2008 GMC Sierra 1500. I have been looking at different brands and I was wondering what was the best quality for the best price? I have looked at LPP, OBX, ARH, Pacesetter, and CalSpeed Performance. I would love to hear what you guys think. If you have another brand thats good, feel free to let me know. I'm trying to spend under $500.
